Note: these chips contain a 0008 device which is incompatible with the
5595. We recognize these by the presence of the listed
"blacklist" PCI ID and refuse to load.

Module Parameters
-----------------
================== =====================================================
force_addr=0xaddr Set the I/O base address. Useful for boards
that don't set the address in the BIOS. Does not do a
PCI force; the device must still be present in lspci.
Don't use this unless the driver complains that the
base address is not set.
================== =====================================================
Description
-----------
i2c-sis5595 is a true SMBus host driver for motherboards with the SiS5595
southbridges.
WARNING: If you are trying to access the integrated sensors on the SiS5595
chip, you want the sis5595 driver for those, not this driver. This driver
is a BUS driver, not a CHIP driver. A BUS driver is used by other CHIP
drivers to access chips on the bus.Annotation

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
